PAPER-FOLDING MACHlNE.

SPECIFICATION forming part of Letters Patent No. 303,255, dated August 12, 1884:.

Application filed October 19, 1883. (No model.)

To all whom it may concern:

Be it known that I, Fennnnro G. BEACH, of Albion, in the county of Orleans and State of New York, have invented a certain new and useful Improvement in Paper-Folding Machines; and I do hereby declare that the follow ingis a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which Figure 1, Sheet 1, isa plan of the paperfoldelr; Fig. 2, Sheet 2, a side elevation of the same, viewed as indicated by arrow 2 in Fig. 1; Fig. 3, Sheet 3, an end elevation of the same, viewed as indicated by arrow y in Fig. 1; Fig. 4, Sheet 4, a side elevation viewed as indicated by arrow w in Fig. l; and Fig. 5,

Sheet 3, a detached figure drawn to a larger scale, showing more clearly the ope-ration of some of its parts.

Similar letters of reference indicate corresponding parts.

My improvement relates to that class of paper-folders in which a series of swinging frames are employed for folding the sheets of paper; and my improvement consists in combining with the frames a knife and two cylinders, also automatic knives of peculiar construction combined with the frames, for creasing the sheet preparatory to the operation of folding. The posts and cross-pieces of the table A constitute the frame-work of the paper-folder. W hen in operation, the folder stands in front of and near the printing-press, from which it receives motion by means of a chain connecting the sprocket-wheel G with a similar wheel attached to the cylinder-shaft folder is so adjusted in relation to the press that the press-fly will deposit the sheet accurately upon the folder.

The manner of operation is as follows: The sheet of paper havingbeen deposited upon the folder by the press-fly, the folder-fly a is caused to describe ahalf-revolution by the operation of the segmental gear m, which engages with the segmental gear 9, attached to the folder-fly. The sheet is thus folded once, and the folder-fly is caused to return to the place by the spring 19. As the folder-fly moves forward, the creasing-blade 7:, which consists of a long prism-shaped knife, is actuated by the spring 2%, so that its sharp edge is adjusted at such an angle that it will form a deep crease in the sheet along the edge of the rod e as the folder-fly is brought down upon the The position of the other folder-flies. The folder-fly or having been returned to its place, the segmental gear a then engages with the segmental gear h to opcrate the folder-fly 2), another fold being made in the sheet, and the creasing-blade Z forming the crease for the next fold along the edge of the rod f. The fly b is returned to its place by the spring o and a second series of teeth on the side of the segmental gear a engage with the segmental gear i to operate the foldcrfly 0 and make the third fold. The fly being returned by the spring 4', the knife E, which is operated by the cam K, in connection with springs, is caused to fall and forces the sheet between the cylinders F F, which convey it to the discharging-fly H, by which'itisthrown into a suitable receptacle. The spri ngs p and 'r are connected 'to the folding-flies by the chains L M N. The creasing-blades are hinged below the surface of the folder-flies. The out side ends of each are provided with a small crank, 20 in, which rests upon a trip of suitable shape when the fly is at rest to cause the creasing-blades to be so inclined that its sharp edge does not project above the surface to interfere with the proper operation of the precedingfly; but as the fly is moved forward the creasing-blade, being released from the trip, is thrown, by the operation of a spring, into position for forming a crease. In the drawings, 1- 1' represent the springs, and q q the trips, which govern the position of the creasing-blades. I A similar creasingblade may also be applied to the press-fly, so as to form a crease along the edge of the rod d for the first fold.' The driving-shaft imparts motion to the shaft It, which is connected to the shaft S by beveled gearing. The cylinders F F are IOC
